BACKGROUND

1. Field

This disclosure relates generally to compounds, pharmaceutical compositions and methods of use of the compounds and compositions containing them. This disclosure relates more particularly to certain carboxamide, sulfonamide and amine compounds and pharmaceutical compositions thereof, and to methods of treating and ameliorating disorders and conditions related to the adiponectin pathway, sphingolipid metabolism, oxidative stress, mitochondrial dysfunction, free radical damage and metabolic inefficiency, among others.

2. Technical Background

The kinase 5′-AMP-activated protein kinase (AMPK) is well established as an important sensor and regulator of cellular energy homeostasis. Being a multi-substrate enzyme, AMPK regulates a variety of metabolic processes, such as glucose transport, glycolysis and lipid metabolism. It acts as a sensor of cellular energy homeostasis and is activated in response to certain hormones and muscle contraction as well as to intracellular metabolic stress signals such as exercise, ischemia, hypoxia and nutrient deprivation. Once activated, AMPK switches on catabolic pathways (such as fatty acid oxidation and glycolysis) and switches off ATP-consuming pathways (such as lipogenesis). Activation of the AMPK pathway improves insulin sensitivity by directly stimulating glucose uptake in adipocytes and muscle and by increasing fatty acid oxidation in liver and muscle, resulting in reduced circulating fatty acid levels and reduced intracellular triglyceride contents. Moreover, activation of the AMPK pathway decreases glycogen concentration by reducing the activity of glycogen synthase. Activation of the AMPK pathway also plays a protective role against inflammation and atherosclerosis. It suppresses the expression of adhesion molecules in vascular endothelial cells and cytokine production from macrophages, thus inhibiting the inflammatory processes that occur during the early phases of atherosclerosis. What is needed are compounds, pharmaceutical compositions and methods of using them to treat disease states wherein AMPK activation is beneficial, such as type II diabetes, atherosclerosis and cardiovascular disease.

The present disclosure contemplates combinations of particularly described embodiments. For example, a first paragraph discloses certain embodiments of ring system “B” and a second paragraph discloses certain embodiments of T; also contemplated are embodiments in which ring system “B” is as described as in the first paragraph and T is as described in the second paragraph. This disclosure contemplates all such combinations, to the extent the definitions of the various structural features do not conflict with one another.

The compounds of the disclosure can be made using synthetic methodology familiar to the person of skill in the art, and using procedures analogous to those described in U.S. Patent Application Publications nos. 2009/0163511, 2009/0170829, 2009/0186894 and 2009/0275609, and in U.S. patent application Ser. Nos. 12/695,861 and 13/194,810, each of which is hereby incorporated by reference in its entirety.

The compounds disclosed herein can be made using procedures familiar to the person of ordinary skill in the art and as described herein. For example, compounds of structural formula (7-I) can be prepared according to Schemes 1-6, below, or analogous synthetic schemes:

Referring to Scheme 1, a pyridinedicarboxylic acid monomethyl ester (i), for example, is coupled with an amine (here a substituted 1-benzoylpiperidine-4-amine) to form a carboxymethyl-substituted pyridinecarboxamide (ii). The ester is saponified to form the corresponding carboxylic acid (iii), which is then coupled with a suitable amine (in this case, a substituted 1-benzylpiperazine) to form a compound of structural formula (7-I).

Referring to Scheme 2, a bromopyridinedicarboxylic acid, for example, is coupled with an amine (here a substituted 1-benzylpiperidine-4-amine) to form a bromo-substituted pyridinecarboxamide (iv), which is then coupled with a suitable amine (in this case, a substituted 4-phenoxypiperidine) using a palladium catalyst to form a compound of structural formula (7-I).

Referring to Scheme 3, a pyridinedicarboxylic acid monomethyl ester (v), for example, is coupled with an amine (here a substituted 1-benzylpiperidine-4-amine) to form a carboxymethyl-substituted pyridinecarboxamide (vi). The ester is saponified to form the corresponding carboxylic acid (vii), which is then coupled with a suitable amine (in this case, a substituted 4-benzoylpiperidine) to form a compound of structural formula (7-I).

Referring to Scheme 4, a pyridine dicarboxylic acid (viii), for example, is coupled with one equivalent of an amine (here, a substituted 1-benzylepiperizine), then with methanol and trimethylsilyl(diazomethane) to form a carbomethoxy-substituted pyridinecarboxamide (ix), which is saponified to give a carboxylic acid-substituted pyridinecarboxamide (x). An amine (in this case, 1-phenylpiperazine) is coupled with the carboxylic acid-substituted pyridinecarboxamide (x) to form a compound of structural formula (7-I).

Referring to Scheme 5, a bromopyridinecarboxamide (xi) is coupled with a substituted 1-benzylpiperidine-4-carboxamide using a palladium catalyst to form Compound 46 of Table 1. Reactions of this general type are described in more detail, for example, in Wrona, Iwona E. et al., Journal of Organic Chemistry (2010), 75(9), 2820-2835.

Scheme 6 describes a preparation that can be used to make gem-dimethylpiperazines for use in making compounds analogous to Compound 125 of Table 1. A piperazin-2-one is singly protected with trityl chloride, then coupled with an appropriate bromide (here, a substituted benzyl bromide) to form a 4-protected 1-(substituted benzyl)piperazin-2-one. The oxo is converted to a gem-dimethyl using Grignard chemistry, then the trityl is removed to yield the desired gem-dimethyl piperazine. Details are provided in the Examples below, and in Xiao, K-J.; Luo, J-M.; Ye, K-Y.; Wang, Y.; Huang, P-Q. Angew. Chem. Int. Ed. 2010, 49, 3037-3040.

Moreover, compounds with methyl-substituted piperidine moieties can be prepared using procedures analogous to those described in Scheme 7, below.

Scheme 7 describes a preparation that can be used to make 1-Boc-3,3-dimethylpiperidin-4-one and 1-Boc-3,3-dimethylpiperidine-4-amine, which can further be elaborated into a variety of compounds, such as Compound 7-83 of Table 7. In Scheme 7, a benzyl-protected piperidinone is methylated at the 3-position with iodomethane, and the benzyl protecting group is removed by hydrogenolysis and replaced with a butyloxycarbonyl (Boc) protecting group to form 1-Boc-3,3-dimethylpiperidin-4-one (a). The carbonyl can be reductively aminated with benzyl amine, which yields 1-Boc-3,3-dimethylpiperidin-4-amine (b) upon hydrogenolysis. In this example, 1-Boc-3,3-dimethylpiperidin-4-amine is coupled with a substituted pyridinecarboxylic acid (c), the Boc group is removed, and the piperidine nitrogen is alkylated to form Compound 7-83.

Similar procedures can be used to convert commercially available 1-benzyl-3-methylpiperidin-4-one to 1-Boc-3-methylpiperidin-4-amine; using the procedures described herein, the major diastereomer is the cis diastereomer. Similarly, commercially available 1-Boc-3,3-difluoro can be converted to 1-Boc-3,3-difluoropiperidin-4-amine

As shown in Scheme 8, similar procedures can be used to convert 1-Boc-3-trifluoromethylpiperidin-4-one to 1-Boc-3-trifluoromethylpiperidin-4-amine 1-Boc-3-trifluoromethylpiperidin-4-one can be prepared from 1-methyl-4-(triethylsilyloxy)-1,2,3,6-tetrahydropyridine as described in Pham, P. V., et al., Angew. Chem. Int. Ed. 2011, 50, 6119-6122, which is hereby incorporated herein by reference in its entirety.

As shown in Scheme 9, similar procedures can be used to convert 1-benzyl-3,5-dimethylpiperidin-4-one amine to 1-Boc-3,5-dimethylpiperidin-4-amine; use of the procedures described herein, a 3:1 ratio of diastereomers at the 4-position is achieved. 1-Boc-3,5-dimethylpiperidin-4-amine can be prepared by alkylation of commercially available 1-benzyl-3-methylpiperidin-4-one; the syn diastereomer is a minor reaction product.

Scheme 10 describes a preparation that can be used to make substituted cyanobenzaldehydes that can be used in the construction of the G-R¹⁷ moiety, for example, by reductive amination. For example, in Scheme 10, 4-bromo-2-methoxybenzonitrile is vinylated to form 1-vinyl-4-cyano-3-methoxybenzene. The vinyl double bond is cleaved with osmium tetraoxide. to form 4-cyano-3-methoxybenzaldehyde. Similarly, 4-cyano-3-methylbenzaldehyde, 3-cyano-4-methylbenzaldehyde, 4-cyano-2-methylbenzaldehyde, 3-cyano-4-methoxybenzaldehyde and 5-cyano-2-methoxybenzaldehyde can be prepared from their corresponding bromides.

For use in the synthesis of various compounds described above, (cis)- and (trans)-tert-butyl 4-amino-3-fluoropiperidine-1-carboxylate can be prepared as described in Scheme 11 below:

Scheme 12 provides an example of a synthetic route for the preparation of benzofurandicarboxamide compounds:

Scheme 13 provides an example of a synthetic route for the preparation of (carboxamido)benzofurancarboxamide compounds:

Scheme 14 provides an example of a synthetic route for the preparation of (3-fluoropiperidin-4-yl)oxybenzofurancarboxamide compounds:

For simplicity, chemical moieties are defined and referred to throughout primarily as univalent chemical moieties (e.g., alkyl, aryl, etc.). Nevertheless, such terms are also used to convey corresponding multivalent moieties under the appropriate structural circumstances clear to those skilled in the art. For example, while an “alkyl” moiety can refer to a monovalent radical (e.g. CH₃—CH₂—), in some circumstances a bivalent linking moiety can be “alkyl,” in which case those skilled in the art will understand the alkyl to be a divalent radical (e.g., —CH₂—CH₂—), which is equivalent to the term “alkylene.” (Similarly, in circumstances in which a divalent moiety is required and is stated as being “aryl,” those skilled in the art will understand that the term “aryl” refers to the corresponding divalent moiety, arylene). All atoms are understood to have their normal number of valences for bond formation (i.e., 4 for carbon, 3 for N, 2 for O, and 2, 4, or 6 for S, depending on the oxidation state of the S). Nitrogens in the presently disclosed compounds can be hypervalent, e.g., an N-oxide or tetrasubstituted ammonium salt. On occasion a moiety may be defined, for example, as (A)_(a)-B-, wherein a is 0 or 1. In such instances, when a is 0 the moiety is B- and when a is 1 the moiety is A-B-.

As used herein, the term “alkyl” includes alkyl, alkenyl and alkynyl groups of a designed number of carbon atoms, desirably from 1 to about 12 carbons (i.e., inclusive of 1 and 12). The term “C_(m)-C_(n) alkyl” means an alkyl group having from m to n carbon atoms (i.e., inclusive of m and n). The term “C_(m)-C_(n) alkyl” means an alkyl group having from m to n carbon atoms. For example, “C₁-C₆ alkyl” is an alkyl group having from one to six carbon atoms. Alkyl and alkyl groups may be straight or branched and depending on context, may be a monovalent radical or a divalent radical (i.e., an alkylene group). In the case of an alkyl or alkyl group having zero carbon atoms (i.e., “C₀ alkyl”), the group is simply a single covalent bond if it is a divalent radical or is a hydrogen atom if it is a monovalent radical. For example, the moiety “—(C₀-C₆ alkyl)-Ar” signifies connection of an optionally substituted aryl through a single bond or an alkylene bridge having from 1 to 6 carbons. Examples of “alkyl” include, for example, methyl, ethyl, propyl, isopropyl, butyl, iso-, sec- and tert-butyl, pentyl, hexyl, heptyl, 3-ethylbutyl, 3-hexenyl and propargyl. If the number of carbon atoms is not specified, the subject “alkyl” or “alkyl” moiety has from 1 to 12 carbons.

The term “haloalkyl” is an alkyl group substituted with one or more halogen atoms, e.g. F, Cl, Br and I. A more specific term, e.g., “fluoroalkyl” is an alkyl group substituted with one or more fluorine atoms. Examples of “fluoroalkyl” include fluoromethyl, difluoromethyl, trifluoromethyl, pentafluoroethyl, hexafluoroisopropyl and the like. In certain embodiments of the compounds disclosed herein, each haloalkyl is a fluoroalkyl.

The term “aryl” represents an aromatic ring system having a single ring (e.g., phenyl) which is optionally fused to other aromatic hydrocarbon rings or non-aromatic hydrocarbon rings. “Aryl” includes ring systems having multiple condensed rings and in which at least one is carbocyclic and aromatic, (e.g., 1,2,3,4-tetrahydronaphthyl, naphthyl). Examples of aryl groups include phenyl, 1-naphthyl, 2-naphthyl, indanyl, indenyl, dihydronaphthyl, fluorenyl, tetralinyl, and 6,7,8,9-tetrahydro-5H-benzo[a]cycloheptenyl. In certain examples, aryl groups include those having a first carbocyclic, aromatic ring fused to an aromatic or aliphatic heterocycle, for example, 2,3-dihydrobenzofuranyl. The aryl groups herein are unsubstituted or, when specified as “optionally substituted”, can unless stated otherwise be substituted in one or more substitutable positions with various groups, as described below.

The compounds disclosed herein can also be provided as pharmaceutically acceptable salts. The term “pharmaceutically acceptable salts” or “a pharmaceutically acceptable salt thereof” refer to salts prepared from pharmaceutically acceptable non-toxic acids or bases including inorganic acids and bases and organic acids and bases. If the compound is basic, salts may be prepared from pharmaceutically acceptable non-toxic acids. Such salts may be, for example, acid addition salts of at least one of the following acids: benzenesulfonic acid, citric acid, α-glucoheptonic acid, D-gluconic acid, glycolic acid, lactic acid, malic acid, malonic acid, mandelic acid, phosphoric acid, propanoic acid, succinic acid, sulfuric acid, tartaric acid (d, l, or dl), tosic acid (toluenesulfonic acid), valeric acid, palmitic acid, pamoic acid, sebacic acid, stearic acid, lauric acid, acetic acid, adipic acid, carbonic acid, 4-chlorobenzenesulfonic acid, ethanedisulfonic acid, ethylsuccinic acid, fumaric acid, galactaric acid (mucic acid), D-glucuronic acid, 2-oxo-glutaric acid, glycerophosphoric acid, hippuric acid, isethionic acid (ethanolsulfonic acid), lactobionic acid, maleic acid, 1,5-naphthalene-disulfonic acid, 2-naphthalene-sulfonic acid, pivalic acid, terephthalic acid, thiocyanic acid, cholic acid, n-dodecyl sulfate, 3-hydroxy-2-naphthoic acid, 1-hydroxy-2-naphthoic acid, oleic acid, undecylenic acid, ascorbic acid, (+)-camphoric acid, d-camphorsulfonic acid, dichloroacetic acid, ethanesulfonic acid, formic acid, hydriodic acid, hydrobromic acid, hydrochloric acid, methanesulfonic acid, nicotinic acid, nitric acid, orotic acid, oxalic acid, picric acid, L-pyroglutamic acid, saccharine, salicylic acid, gentisic acid, and/or 4-acetamidobenzoic acid.

The compounds described herein can also be provided in prodrug form. “Prodrug” refers to a derivative of an active compound (drug) that undergoes a transformation under the conditions of use, such as within the body, to release the active drug. Prodrugs are frequently, but not necessarily, pharmacologically inactive until converted into the active drug. Prodrugs are typically obtained by masking a functional group in the drug believed to be in part required for activity with a progroup (defined below) to form a promoiety which undergoes a transformation, such as cleavage, under the specified conditions of use to release the functional group, and hence the active drug. The cleavage of the promoiety can proceed spontaneously, such as by way of a hydrolysis reaction, or it can be catalyzed or induced by another agent, such as by an enzyme, by light, by acid, or by a change of or exposure to a physical or environmental parameter, such as a change of temperature. The agent can be endogenous to the conditions of use, such as an enzyme present in the cells to which the prodrug is administered or the acidic conditions of the stomach, or it can be supplied exogenously. A wide variety of progroups, as well as the resultant promoieties, suitable for masking functional groups in the active drugs to yield prodrugs are well-known in the art. For example, a hydroxyl functional group can be masked as a sulfonate, ester or carbonate promoiety, which can be hydrolyzed in vivo to provide the hydroxyl group. An amino functional group can be masked as an amide, carbamate, imine, urea, phosphenyl, phosphoryl or sulfenyl promoiety, which can be hydrolyzed in vivo to provide the amino group. A carboxyl group can be masked as an ester (including silyl esters and thioesters), amide or hydrazide promoiety, which can be hydrolyzed in vivo to provide the carboxyl group. Specific examples of suitable progroups and their respective promoieties will be apparent to those of skill in the art.

The compounds disclosed herein can also be provided as N-oxides.

The presently disclosed compounds, salts, prodrugs and N-oxides can be provided, for example, in solvate or hydrate form.

One of ordinary skill in the art of medicinal chemistry also will appreciate that the disclosed structures are intended to include isotopically enriched forms of the present compounds. As used herein “isotopes” includes those atoms having the same atomic number but different mass numbers. As will be apparent to those of skill in the art upon consideration of the present compounds, certain atoms can be enriched an isotope of that atom. For example, compounds having a fluorine atom, may be synthesized in a form enriched in the radioactive fluorine isotope ¹⁸F. Similarly, compounds may be enriched in the heavy isotopes of hydrogen, deuterium and tritium, and can be enriched in a radioactive isotope of carbon, such as ¹³C. Such compounds can be useful, for example, in studying the AMPK pathway and its role in metabolism.

Compounds can be assayed for binding to a membrane-bound adiponectin receptor by performing a competitive binding assay with adiponectin. In one such procedure, HEK 293 cellular membrane is coated onto a COSTAR 384 plate, which is then blocked with 1% casein. Polyhistidine-tagged globular adiponectin and a candidate compound is incubated with the membrane in HEPES buffer. Unbound ligands are washed away and the degree of binding of the adiponectin is determined using horseradish peroxidase-conjugated anti-polyhistidine. Compounds that compete with adiponectin binding to the membrane (i.e., give a reduced signal compared to a control performed without a candidate compound) can be chosen as hits and further screened using the below-described functional assays to identify adiponectin receptor agonists.

An in-cell western assay can be performed to demonstrate the activation of AMPK in human liver cells by globular adiponectin using glutathione S-transferase (GST). AMPK activity can be measured by the relative concentration of phosphorylated acetyl Co-A carboxylase, which is one of the products of AMPK. An increase in pACC correlates with an increase in the rate of fatty acid oxidation.

The compounds disclosed herein can be administered, for example, orally, topically, parenterally, by inhalation or spray or rectally in dosage unit formulations containing one or more pharmaceutically acceptable carriers, diluents or excipients. The term parenteral as used herein includes percutaneous, subcutaneous, intravascular (e.g., intravenous), intramuscular, or intrathecal injection or infusion techniques and the like.

Pharmaceutical compositions can be made using the presently disclosed compounds. For example, in one embodiment, a pharmaceutical composition includes a pharmaceutically acceptable carrier, diluent or excipient, and compound as described above.

The presently disclosed compounds can also be administered in the form of suppositories, e.g., for rectal administration of the drug. These compositions can be prepared by mixing the compound with a suitable non-irritating excipient that is solid at ordinary temperatures but liquid at the rectal temperature and will therefore melt in the rectum to release the drug. Such materials include cocoa butter and polyethylene glycols.

The presently disclosed compounds can also be administered parenterally in a sterile medium. The drug, depending on the vehicle and concentration used, can either be suspended or dissolved in the vehicle. Advantageously, adjuvants such as local anesthetics, preservatives and buffering agents can be dissolved in the vehicle.

The compounds disclosed herein can be made using procedures familiar to the person of ordinary skill in the art and as described, for example, in U.S. Patent Application Publications nos. 2009/0163511, 2009/0170829, 2009/0186894 and 2009/0275609, and in U.S. patent application Ser. No. 12/695,861, each of which is hereby incorporated by reference in its entirety. One of skill in the art can adapt the reaction sequences described therein to fit the desired target molecule. Of course, in certain situations one of skill in the art will use different reagents to affect one or more of the individual steps or to use protected versions of certain of the substituents. Additionally, one skilled in the art would recognize that the presently disclosed compounds can be synthesized using different routes altogether.

Compounds suitable for use in the presently disclosed pharmaceutical compositions include compounds of Tables 1-7, above.

While not intending to be bound by theory, the inventors surmise that the compounds described herein activate the AMPK pathway, for example by acting as mimics of adiponectin. Activation of the AMPK pathway has the effect of increasing glucose uptake, decreasing glycogen synthesis and increasing fatty acid oxidation, thereby reducing glycogen, intracellular triglyceride and fatty acid concentration and causing an increase in insulin sensitivity. Because they activate the AMPK pathway, the compounds described herein should also inhibit the inflammatory processes which occur during the early phases of atherosclerosis. Accordingly, the compounds described herein can be useful in the treatment of type II diabetes and in the treatment and prevention of atherosclerosis, cardiovascular disease, obesity and non-alcoholic fatty liver disease.

Accordingly, another aspect of the present disclosure relates to a method of activating the AMPK pathway. According to this aspect, a method for activating the AMPK pathway in a cell includes contacting the cell with an effective amount of a compound, pharmaceutically acceptable salt, N-oxide (or solvate or hydrate thereof) or composition described herein.

In one embodiment, a method of increasing fatty acid oxidation in a cell includes contacting the cell with an effective amount of a compound, pharmaceutically acceptable salt, N-oxide (or solvate or hydrate thereof) or composition described herein. Acetyl Co-A carboxylase (ACC) catalyzes the formation of malonyl Co-A, a potent inhibitor of fatty acid oxidation; phosphorylation of ACC greatly reduces its catalytic activity, thereby reducing the concentration of malonyl Co-A and increasing the rate of fatty acid oxidation. Because the presently disclosed compounds can increase the rate of phosphorylation of ACC, they can reduce the inhibition of fatty acid oxidation and therefore increase its overall rate.

In another embodiment, a method of decreasing glycogen concentration in a cell includes contacting the cell with an effective amount of a compound, pharmaceutically acceptable salt, N-oxide (or solvate or hydrate thereof) or composition described herein.

In another embodiment, a method of increasing glucose uptake in a cell includes contacting the cell with an effective amount of a compound, pharmaceutically acceptable salt, N-oxide (or solvate or hydrate thereof) or composition described herein.

In another embodiment, a method of reducing triglyceride levels in a subject includes administering to the subject an effective amount of a compound, pharmaceutically acceptable salt, N-oxide (or solvate or hydrate thereof) or composition described herein.

In another embodiment, a method of increasing insulin sensitivity of a subject includes administering to the subject an effective amount of a compound, pharmaceutically acceptable salt prodrug, N-oxide (or solvate or hydrate thereof) or composition described herein.

Accordingly, the compounds and compositions disclosed herein can be used to treat a variety of metabolic disorders. For example, in one embodiment, a method of treating type II diabetes in a subject in need of such treatment includes administering to the subject an effective amount of a compound, pharmaceutically acceptable salt, solvate, hydrate, N-oxide or composition described herein. In another embodiment, a method of treating or preventing atherosclerosis or cardiovascular disease in a subject includes administering to the subject an effective amount of a compound, pharmaceutically acceptable salt prodrug, N-oxide (or solvate or hydrate thereof) or composition described herein.

As described herein, the compounds disclosed herein can act as activators of the AMPK pathway. Accordingly, in another embodiment, a method comprises modulating the AMPK pathway (either in vitro or in vivo) by contacting a cell with a compound, pharmaceutically acceptable salt, N-oxide (or solvate or hydrate thereof) or composition described herein, or administering a compound, pharmaceutically acceptable salt, N-oxide (or solvate or hydrate thereof) or composition described herein to a mammal (for example, a human) in an amount sufficient to modulate the AMPK activity and study the effects thereby induced. Such methods are useful for studying the AMPK pathway and its role in biological mechanisms and disease states both in vitro and in vivo.

In certain embodiments, the compounds disclosed herein affect lipid signaling pathways. For example, in some embodiments, the compounds up-regulate ceramidase activity. Ceramide is a central player in sphingolipid metabolism, and is the immediate precursor of sphingomyelins and glycosphingolipids as well as the bioactive products sphingosine and sphingosine-1-phosphate. Moreover, endogenous ceramide itself mediates, at least in part, the actions of a variety of stimuli on cell differentiation, apoptosis, and growth suppression. Ceramide is deacylated by ceramidase to form sphingosine, which is in turn phosphorylated to sphingosine-1-phosphate by sphingosine kinase.

Elevated ceramide levels have been shown to induce cell apoptosis, differentiation and senescence. Moreover, elevated ceramide levels are linked to a variety of diseases and disorders, including, for example, Batten's disease, inflammatory bowel diseases, diffuse intravascular coagulation, fever, protein catabolism and/or lipid depletion, hepatosplenomegaly associated with inflammatory or metabolic liver diseases, endomyocarditis, endolithial cell and leucocyte activation, capillary thrombosis, meningo-encephalitis due to infectious agents, complications in organ transplantation, rheumatoid arthritis and connective tissue diseases, autoimmune diseases, hyperthyroidism, damage by radiation/chemotherapy agents and chronic fatigue syndrome.

Up-regulating ceramidase function (and therefore reducing the concentration of ceramide) can be used to treat disorders involving deficient cell proliferation (growth) or in which cell proliferation is otherwise desired, for example, degenerative disorders, growth deficiencies, lesions, physical trauma, and diseases in which ceramide accumulates within cells, such as Fabry disease. Other disorders that may benefit from the activation of ceramidase include neurodegenerative disorders such as Alzheimer's disease and amyotrophic lateral sclerosis and disorders of aging such as immune dysfunction, as well as disorders, such as those listed above, linked to elevated ceramide levels.

The compounds, salts, prodrugs, N-oxides, solvates and hydrates described herein can be administered, for example, to a mammalian host to retard cellular responses associated with the activation of the ceramide-mediated signal transduction pathway. The compounds can be useful, for example, in providing protection against cell senescence or apoptosis, such as occurs as a result of trauma (for example, radiation dermatitis) and aging (for example, of the skin or other organs).

Another embodiment is a method for up-regulating ceramidase function in a cell (either in vivo or in vitro), the method including contacting the cell with an effective amount of a compound, pharmaceutically acceptable salt, N-oxide (or solvate or hydrate thereof) or composition described herein.

In another embodiment, a method for decreasing ceramide concentration in a cell (either in vivo or in vitro) includes contacting the cell with an effective amount of a compound, pharmaceutically acceptable salt, N-oxide (or solvate or hydrate thereof) or composition described herein.

In another embodiment, a method for inhibiting ceramide-activated responses to stimuli in a cell (either in vivo or in vitro) includes contacting the cell with an effective amount of a compound, pharmaceutically acceptable salt, N-oxide (or solvate or hydrate thereof) or composition described herein. The stimuli can be, for example, stimuli for cell senescence and/or apoptosis.

Another embodiment is a method for treating or preventing a disease or disorder in which cell proliferation is deficient or desired in a subject, the method including administering to the subject an effective amount of a compound, pharmaceutically acceptable salt, N-oxide (or solvate or hydrate thereof) or composition described herein. Various applicable diseases and disorders are described herein.

Another embodiment is a method for treating a disease or disorder linked to elevated ceramide levels in a subject, the method including administering to the subject an effective amount of a compound, pharmaceutically acceptable salt, N-oxide (or solvate or hydrate thereof) or composition as described herein. Various applicable diseases and disorders are described herein. In certain embodiments, the subject has a ceramide level higher than about 50 pmol/10⁶ cells.

Moreover, since some drugs can induce high levels of ceramide, the compounds, salts, prodrugs, N-oxides, solvates and hydrates described herein can be usefully co-administered with such drugs in order to at least partially ameliorate this effect. For example, in certain embodiments, an effective amount of a compound, pharmaceutically acceptable salt, N-oxide (or solvate or hydrate thereof) or composition as described herein is co-administered with a corticosteroid (for example, dexamethasone), an anti-inflammatory (for example, indomethacin), an antiviral (for example, interfereon), an immunosuppressant (for example, cyclosporin), a chemotherapy agent (for example, adriamicin), and immunopotentiant (for example, an immunoglobulin or a vaccine), or an andocrinological agent (for example, metimazole). As the person of skill in the art will appreciate, co-administration contemplates not only administration at the same time, but also administration at different times, but with time-overlapping pharmacological effects.

Another embodiment is a method for reducing the effect of aging in the skin of a subject, the method including contacting the skin with a compound, pharmaceutically acceptable salt, N-oxide (or solvate or hydrate thereof) or composition as described herein.

Another embodiment is a method for treating or preventing radiation dermatitis in the skin of a subject, the method including contacting the skin with a compound, pharmaceutically acceptable salt, N-oxide (or solvate or hydrate thereof) or composition as described herein.

To identify and select therapeutic compounds for use in treating ceramide-associated conditions, cells (or intracellular components such as microsomes) which have not been exposed to a senescence or apoptosis-inducing agent (for example, cytokines such as TNF-α or exogenous stimuli such as heat, radiation or chemical agents) are exposed to such and agent and to the candidate compound. Inhibition of senescence or apoptosis is measured as a function of cell growth. The person of ordinary skill in the art will be familiar with techniques for obtaining such measurements.

For example, inhibition of cell senescence can be measured after serum deprivation in serum-dependent cells. Many cell types are dependent upon serum factors for growth. Thus, deprivation of such cells of serum provides a model for assessment of compounds to modulate cell responses to intracellular ceramide-mediated signal transduction. In particular, withdrawal of serum from serum-dependent cell cultures produces increased intracellular levels of endogenous ceramide and may also increase intracellular levels of endogenous diacyl glycerol (see, e.g., Jayadev, et al., J. Biol. Chem., 270, 2047-2052 (1995)). To evaluate the inhibitory effect of the compounds described herein on ceramide-associated conditions in vitro, the serum withdrawal model can be used. Specifically, 3T3 fibroblast cells can be seeded in 96 well microtiter plates in DMEM in the presence of 10% fetal bovine serum. The cells are incubated to 90% confluence. The medium is removed, and the cells washed and reincubated in serum-free DMEM. A test compound at a variety of concentrations (for example, 0, 4, 40 or 400 μM) and cell permeable ceramide (for example, 0, 5 or 10 μM) are added to the wells. After 24 hrs. incubation, 0.5 μCi of [³H] thymidine is added to each well for 2 hrs. DNA synthesis in the tested cell population is assessed by conventional techniques for detection of [³H] thymidine incorporation. The results of this assay can be used to establish the cell senescence inhibitory efficacy of the test compound.

Inhibition of cell apoptosis can be determined, for example, using CD95 stimulation. Engagement of cell surface receptor CD95 (also known as Fas/Apo-1 antigen) triggers cell apoptosis. DX2 is a functional anti-FAS (CD95) antibody which will, on binding of CD95, activate the sphingomyelinase catalysis of sphingomyelin hydrolysis and production of ceramide (see, with respect to DX2, Cifone, et al., J. Exp. Med., 177, 1547-1552 (1993)). Thus, binding of CD95 is a model for conduction of apoptosis via the sphingomyelin signal transduction pathway. To assess the inhibitory effect of the compounds disclosed herein on ceramide-mediated cell apoptosis, human T lymphoblasts (Jurkat) are suspended at 2×10⁶ cells/mL in RPMI-1640 supplemented with insulin, transferrin, selenium and glutamine. After incubation for 2 hrs. at room temperature with a test compound, pentoxifylline or a control compound (Ro-1724), 25 ng/mL of anti-FAS antibody is added to each suspension. After another 2 hrs., cell apoptosis is measured as a function of the number of cells (counted by hemocytometer) that excluded the vital dye erythrosin B. The results of the experiment can be used to establish the apoptosis inhibitory efficacy of the test compound.

To assess the inhibitory effect of the compounds disclosed herein on death of human lymphocytes, human peripheral blood lymphocytes are isolated from normal human blood and depleted of monocytes by adherence to a plastic substrate. Lymphocytes are then cultured in RPMI-1640 medium with 10% autologous plasma at an initial concentration of 2×10⁶ cells/mL. Aliquots of the cell samples are divided and one half of the samples are incubated with a test compound or 6,7-dimethoxy-1(2H)-isoquinoline (Aldrich) for four days. The remaining half of the samples are allowed to rest for four days. Cell viability after four days is determined by erythrosin B dye exclusion in a hemocytometer. The results of the experiment can be used to establish the apoptosis inhibitory efficacy of the test compound on human lymphocytes as compared to untreated lymphocytes.

Ceramide-activated protein kinase (CaPK) is a 97 kDa protein which is exclusively membrane-bound and is believed to serve a role in the sphingomyelin signal transduction pathway. In particular, CaPK is believed to mediate phosphorylation of a peptide derived from the amino acid sequence surrounding Thr.sup.669 of the epidermal growth factor receptor (i.e., amino acids 663-681). This site is also recognized by the mitogen-activated kinase MAP (also known as a family of extracellular signal-regulated kinases). Thus, the effect of the compounds disclosed herein on CaPK activity in cells can be indicative of the effect that the compounds exert on signal transduction in the sphingomyelin pathway. Accordingly, Jurkat cells are suspended at 2×10⁶ cells/mL in RPMI-1640 medium as described herein with respect to the cell apoptosis experiment. After incubation for 2 hrs., either a test compound; 20 μM of ceramide or 25 ng/ml of anti-FAS antibody DX2 are added to each suspension and incubated for 15 mins. After centrifugation and washing, the cells were separately homogenized in a dounce homogenizer. Ceramide kinase levels in each test sample can be assayed as described by Liu, et al., J. Biol. Chem., 269, 3047-3052 (1994), which is hereby incorporated by reference herein in its entirety. Briefly, the membrane fraction is isolated from each test sample of treated cell homogenate by ultracentrifugation and run on a 10% PAGE gel. The gel is washed with guanadine-HCl, and renatured in HEPES buffer. Then [³²P]-ATP is added to the gel and left there for 10 mins. Thereafter, the gel is extensively washed with 5% TCA. Autophosphorylated kinase is detected by autoradiography. The results of this assay can be used to establish the CaPK inhibitory efficacy of the compounds disclosed herein.

Ceramidase activity can be measured in a variety of ways. For example, a sample from a subject or a sample of cells can be assayed in vitro for RNA or protein levels, structure, and/or activity of the expressed ceramidase RNA or protein. Many methods standard in the art can be thus employed, including but not limited to ceramidase enzyme assays.

Cellular ceramide levels can be monitored directly, or by indirectly monitoring the concentrations of a ceramide metabolite in a cell. For example, ceramide levels can be directly measured by isolating peripheral blood lymphocytes from a subject. The cells are centrifuged to remove supernatant, and lipids are removed from the cell pellet. The organic phase containing the ceramide can be assayed using the diacylglycerase kinase assay for phosphorylating the ceramide which is then evidenced by autoradiography. Methods for performing diacylglycerase kinase assays are described, for example, in Cifone, M. G. et al., J. Exp. Med., 180(4), 1547-52 (1993), Jayadev et al., J. Biol. Chem., 270, 2047-2052. (1995), and Perry, D. K. et al, Methods Enzymology, 312, 22-31 (2000), each of which is hereby incorporated by reference in its entirety.

Another embodiment is the use of a compound, pharmaceutically acceptable salt, N-oxide (or solvate or hydrate thereof) or composition as described herein in the manufacture of a medicament for any of the therapeutic purposes described herein. For example, the medicament can be for the reduction of triglyceride levels in a subject, the treatment of type II diabetes in a subject, or the treatment or prevention of atherosclerosis or cardiovascular disease in a subject. In other embodiments, the medicament can be used to reduce the levels of cellular ceramide in a subject, for example in the treatment of Batten's disease.

For example, free radical damage has been implicated in neurological disorders, such as Parkinson's disease, amyotrophic lateral sclerosis (Lou Gehrig's disease) and Alzheimers disease. Additional diseases in which excessive free radical damage occurs generally include hypoxic conditions and a variety of other disorders. More specifically, such disorders include ischemia, ischemic reperfusion injury (such as coronary or cerebral reperfusion injury), myocardial ischemia or infarction, cerebrovascular accidents (such as a thromboembolic or hemorrhagic stroke) that can lead to ischemia in the brain, operative ischemia, traumatic hemorrhage (for example, a hypovolemic stroke that can lead to CNS hypoxia or anoxia), resuscitation injury, spinal cord trauma, inflammatory diseases, autoimmune disorders (such as rheumatoid arthritis or systemic lupus erythematosis), Down's syndrome, Hallervorden-Spatz disease, Huntingtons chorea, Wilson's disease, diabetic angiopathy (such as peripheral vascular disease or retinal degeneration), uveitis, chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema, asthma, neoplasia, Crohn's disease, inflammatory bowel disease and pancreatitis.

After 4 h the reaction mixture was diluted with EtOAc and washed with saturated aqueous sodium bicarbonate solution, water and brine (2×). The organic layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure to give crude Compound P of Scheme 14, which showed LCMS m/z 577.48 [M+H]+ as required. Compound P was treated with CH₂Cl₂/TFA, 1/1 (10 mL) at RT for 3 h. The solvent was removed under vacuum and the residue was then partitioned between CH₂Cl₂ and saturated aqueous potassium carbonate.

Male C57B/6J mice (8 weeks old) are randomly divided into at least four cohorts for exercise-trained and sedentary control and dosage groups.

Mice are acclimated to moderate treadmill running (10 m/min for 15 min) every other day for 1 week (day 1, 3, 5, 7). After acclimation, basal running endurances for the four groups are determined via a treadmill running test, where the speed is gradually increased from 0 to 15 m/min over the course of 15 min and then maintained constant until exhaustion. Treadmill to be used is 1012M-8-E52 Modular Enclosed Metabolic Treadmill for Mice, 8 Lanes w/Shock for Mice w/Shocker Detection & Software from Columbus Instruments or similar (with attached open-flow calorimeter for the measurement of respiratory metabolic performance while exercising). Exhaustion defined when mice are unable to avoid repetitive electrical shocks. Data are collected on total time and distance run as well as VO₂.

On day 8 dosing by gavage with the compounds begins for the sedentary and exercise-trained groups and dosing with vehicle only for the control sedentary and exercise-trained groups.

Beginning on day 9, the groups to be exercise-trained are subjected to 4 weeks (5 days/week) of exercise training. During all exercise sessions and treadmill tests, VO₂ is measured before, during, and after exercise by means of indirect calorimetry in metabolic treadmill chambers. The 5th day of training for each weekly exercise regime is used as a complete treadmill test where the speed is gradually increased from 0 to 15 m/min over the course of 15 min and then maintained constant until exhaustion. Day 9 exercise to consist of treadmill running of 10 m/min for 15 min with a treadmill incline of 5 degrees. Subsequent exercise-training is to be progressive with increasing intensity and time (also incline of 5 degrees on treadmill). Data are collected on total time and distance for each training session, with point of exhaustion noted for mice failing to complete exercise.

Treatment with the present compounds results in increased endurance for both the exercise-trained and sedentary groups.
